| circuit | a continuous path through which electric charges flow |
| conduction | the transfer of thermal energy that results from the collision of particles |
| convection | the transfer of thermal energy through the movement of a liquid or a gas |
| current electricity | the flow of electric charges through a wire |
| electromagnet | temporary magnet that is made by passing an electric current through a coil of wire that surrounds an iron core |

| insulation | a substance that conducts thermal energy poorly |
| parallel circuit | a circuit in which there is more than one path for the current to follow |
| radiation | the transfer of thermal energy as waves |
| series circuit | a circuit in which there is only one path for the current to follow |
| static electricity | the electrical charge that builds up on an object that has gained or lost electrons |
| thermal energy | the kinetic energy of the moving particles of a substance or object |
